SERVICE SPECIFICATION
In servicing a machine, it is often, useful to
compare that individual units operating
characteristics to those of a normally operating
machine. The data that follows gives those
characteristics; however, be aware that these
values are for NEW, CLEAN machine operating
at 21
°
C ambient and 15
°
C water. USE THESE
NUMBERS AS A GUIDELINE ONLY.
OPERATING CHARACTERISTICS
On air-cooled models during the freezing cycle,
the discharge pressure is maintained between
two preset values by means of fan control
(condenser sensor); and at the same time, the
suction pressure will also decline reaching it’s
lowest point just before harvest. Compressor
amps experience a similar drop.
On water-cooled, the discharge pressure is
constantly, maintained during the freeze cycle by
the water regulating valve. However, suction
pressure and compressor amps, will still decline
as the machine freezes ice.
NOTE: Always check nameplate on individual
icemachine for special refrigerant charge
before charging the refrigeration system.
Such refrigerant charge is the average charge
for the MVP Modular Cubers. However it is
important to check nameplate for each
machine.
